Intercostal muscle - Wikipedia, the free encyclopedia (328 words)
Intercostal muscles are several groups of muscles that run between the ribs, and help form and move the chest wall.
The internal intercostals are responsible for the depression of the ribs decreasing the transverse dimensions of the thoracic cavity.
Both these muscles are innervated by the intercostal nerves (=ventral rami of thoracic spinal nerves), and are provided by the intercostal arteries and veins.
IV. Myology. 6c. The Muscles of the Thorax. Gray, Henry. 1918. Anatomy of the Human Body. (3245 words)
The anterior portions of the Intercostales interni probably have an additional function in keeping the sternocostal and interchondral joint surfaces in apposition, the posterior parts of the Intercostales externi performing a similar function for the costovertebral articulations.
The anterior abdominal muscles come into action so that the umbilicus is drawn upward and backward, but this allows the diaphragm to exert a more powerful influence on the lower ribs; the transverse diameter of the upper part of the abdomen is greatly increased and the subcostal angle opened out.
Deep expiration is effected by the recoil of the walls and by the contraction of the antero-lateral muscles of the abdominal wall, and the Serrati posteriores inferiores and Transversus thoracis.
